ARRAY_SLICE

Introduced or updated: v1.2.762

Extracts a sub-array using slice between start and end arguments.

Syntax

ARRAY_SLICE(array, start, end)

Parameters

Parameter	Description
array	The source array from which to extract a slice.
start	The starting position of the slice (inclusive).
end	The ending position of the slice (exclusive).

Return Type

Array (slice of the original array).

Important Note on Indexing

• For standard array types: Indexing is 1-based (first element is at position 1).
• For variant array types: Indexing is 0-based (first element is at position 0), for compatibility with Snowflake.

Examples

Example 1: Slicing a Standard Array (1-based indexing)

SELECT ARRAY_SLICE([10, 20, 30, 40, 50], 2, 4);

Result:

[20, 30]

Example 2: Slicing a Variant Array (0-based indexing)

SELECT ARRAY_SLICE(PARSE_JSON('["apple", "banana", "orange", "grape", "kiwi"]'), 1, 3);

Result:

["banana", "orange"]

Example 3: Out of Bounds Slice

SELECT ARRAY_SLICE([1, 2, 3], 4, 6);

Result:

[]
